BACKGROUND The biological basis for cancer of unknown primary (CUP) at the molecular level remains largely unknown, with no evidence of whether a common biological entity exists. Here, we assessed the possibility of identifying a common diagnostic biomarker for CUP using a microarray gene expression analysis. METHODS Tumor mRNA samples from 60 patients with CUP were analyzed using the Affymet...
OBJECTIVE To evaluate the scanning laser tomography characteristics of the optic nerve head in patients with primary open angle (POAG) glaucoma using the Heidelberg retina tomography (HRT II). DESIGN A clinic-based retrospective study. PARTICIPANTS A total of 84 eyes of 42 POAG patients with good quality HRT II Images were studied at Charles Nicolle Hospital University department of Ophthal...
INTRODUCTION Many kind of hydroxyapatite-coated cups were used, with favorable results in short term studies; it was supposed that its use could improve osteointegration of the cup, enhancing thus stability and survivorship. The purpose of this study is to analyze the long term behavior of the hemispheric HA coated, Dual Radius Osteonics cup and to discuss the way of failure through the exam of...
The interference press fit of a metallic one-piece acetabular cup employed for metal-on-metal hip resurfacing procedures was investigated experimentally under laboratory conditions in the present study, in particular regarding the cup deformation. Tests were carried out in cadavers as well as polyurethane foams of various grades with different elastic moduli to represent different cancellous bo...
This paper presents a phantom-based study for validating a newly developed 2D-3D reconstruction-based method for measuring implant migration after total hip arthroplasty (THA). Based on a mock-up setup, three different methods were used to determine the cup orientation with respect to the anterior pelvic plane (APP) of a plastic pelvis: (a) the optical tracking method; (b) the fiducial-based me...
In Drosophila, germ cell formation depends on inherited maternal factors localized in the posterior pole region of oocytes and early embryos, known as germ plasm. Here, we report that heterozygous cup mutant ovaries and embryos have reduced levels of Staufen (Stau), Oskar (Osk) and Vasa (Vas) proteins at the posterior pole. Moreover, we demonstrate that Cup interacts with Osk and Vas to ensure ...
Background and purpose - Hip dislocation is one of the most common complications following total hip arthroplasty (THA). Several factors that affect dislocation have been identified, including acetabular cup positioning. Optimal values for cup inclination and anteversion are debatable. We performed a systematic review to describe the different methods for measuring cup placement, target zones f...
Outcome of the Cementless Zweymüller BICON-PLUS Cup and SL-PLUS Stem in the Very Elderly Individuals
INTRODUCTION There is current debate about which type of total hip prosthesis implants are best for the elderly patient. Implanting uncemented total hip arthroplasty (THA) in elderly people remains contested. The aim of present study was to evaluate the outcome of the uncemented Zweymüller BICON-PLUS THA in those with a minimum of 80 years of age. MATERIALS AND METHODS A retrospective data co...
An anisotropic plasticity model is developed based on the non-associated flow rule with hardening. The combines non-quadratic yield function and quadratic plastic potential for orthogonal sheet metals. also expanded to properly reproduce cyclic effect during forming processes. simple formulations can contribute cost saving in parameter acquisition process implementation. was implemented into fi...
INTRODUCTION: Dislocation continues to be a common complication of total hip arthroplasty (THA), affecting 2% to 11% of primary cases. Many factors affect the prevalence of dislocation after THA, including soft tissue laxity, surgical approach, component position, patient factors, and component designs [1,2]. Many in vitro studies have reported the range of motion (ROM) of the hip, impingement,...
